•
OVV
(channel in OVERVOLTAGE condition)
•
UNV
(channel in UNDERVOLTAGE condition)
•
EXTTRIP (channel OFF due to external TRIP line signal)
•
INTTRIP
(channel OFF due to internal OVERCURRENT condition)
•
EXT_DIS (channel disabled by board INTERLOCK protection)
Moreover it is possible to monitor board temperature and to check board status; the
following messages may be returned by the SY 1527 when monitoring the board status:
•
UNDER_TEMP (board temperature < 5°C )
•
OVER_TEMP (board temperature > 65°C)
4.2 Output
Enable
The boards are provided with an "HV EN" input that enables the channels when it is
connected to ground.
When the channels are disabled the voltage outputs drop to zero at the maximum rate
available; when the output disable cause is removed, i. e. the "HV EN" connector is
connected to ground, the channels remain OFF until the User turns them ON via
software.
4.3
Full scale range setting
The output voltage and current full scale range, common to all channels, can be selected
by dip-switches (please refer to the Fig. 4.1 for the dip-switches location on the board).
